How long is the sealant for grout and tile cure or dry?

chuehJuly 3, 2010

I tiled tumbled stones which have a lot of holes and dents. I PRE-sealed the tiles one day after tiling them, because I don't want the holes to be covered by the grout. I plan to grout in another 2 days (3 days after the tiling). Is the sealant going to be dry or cure for 2 days? The instruction on the sealant does not say how long it would dry or how many coats I need.
